Chapter XIII. Tom in Danger

"Garret! Garret Jackson!" cried Tom as he struggled through the hedge of bushes and ran after the men. "Where are you, Garret? Come on and help me chase these men!"

But there came no answer to Tom's hail. He could not hear the sound of the retreating footsteps of the men now and concluded that they had made their escape. Still he would not give up, but dashed on, slipping and stumbling, now and then colliding with a tree.

"What can they be doing here?" thought Tom in great anxiety. "Are they after some more of dad's inventions because they didn't get his turbine motor?"

"Hello! Who's there? Who are you?" called a voice suddenly.

"Oh, Garret! Where have you been?" asked the young inventor, recognizing the tones of his father's keeper. "I've been calling you. Some of those scoundrels are around again!"

"Why if it isn't Tom!" ejaculated the engineer. "However in the world did you get here? I thought you were at Sandport."

"I'll explain later, Garret. Just now I want to catch those men, if I can."

"Is everything all right, Garret?" he concluded. "Dad is nervous and frightened. I must telephone him at the hotel to-night and let him know, for I promised to come back. I can't, though, until to-morrow."

"Everything is all right as far as I know," answered Jackson. "I've kept a careful watch and the burglar alarm has been in working order. Mrs. Baggert and I haven't been disturbed a single night since you went away. It's curious that the men should be here the very night you come back. Maybe they followed you."

"I hardly think so, for they didn't know I was coming."

"You can't tell what those fellows know," commented the engineer. "But, anyhow, I don't suppose they could have gotten here from Sandport as soon as you did."

"Oh, yes they could, in their automobile," declared Tom. "But I don't believe they knew I was coming. They knew we were away, however, and thought it would be a good time to steal something, I guess. Are you sure nothing has been taken?"

"Perfectly sure, but you and I will take a look around the shop."

They made a hasty examination, but found nothing disturbed and no signs that anyone
